In addition to the manufacture of structural alloys based on iron, powder metallurgy is widely used for obtaining materials based on non-ferrous metals, such as porous bronze for self-lubricating bearings, ceramics (aluminum oxides and titanium) for engines, chemical and medical products, magnetic materials, etc.
Non-ferrous metals and their alloys are very popular, widely used in all branches of industry and agriculture. These are all metals except iron and its derivatives, which are classified as ferrous metals.
Virtually all non-ferrous metals have the following properties:
- resistant to corrosion and significant temperature changes;
- versatile applications.
Furthermore, an important feature of non-ferrous metals is that their properties can be modified by quenching, artificial aging or heat treatment. They are also well handled by stamping, rolling, forging, welding, soldering, pressing and cutting.
